Herpetic gingivostomatitis is a mucocutaneous infection caused by herpes virus. It most commonly occurs in childhood and may manifest with symptoms such as pain and fever. Typical findings include vesicles at the site of inoculation. Diagnosis is made by clinical and microbiological evaluation. Symptomatic and antiviral therapy are sometimes needed and the infection may recur later in life.
The incubation period for herpes virus infection is between 2-20 days , but the average time between the contraction of the virus and the appearance of symptoms is about 6 days. Herpetic gingivostomatitis is characterized by a sudden onset of pain, with or without fever, accompanied by other symptoms that are less common and include headache, nausea, malaise, and lymphadenopathy  .
Gingivostomatitis may be also accompanied by pharyngitis, which can result in symptoms related to pain when swallowing. Secondary bacterial infections may also occur, which can result in the appearance of pus-filled erythematous vesicles, although it is not common.
The hallmark of this infection is the abrupt appearance of initially erythematous skin, followed by formation of intraoral, perioral or gingival whitish or yellowish vesicles that are usually grouped, or even umbilicated. They are transient, often fragile, and rupture within the first few days. Unilateral presentation is observed in virtually all cases. These lesions spontaneously resolve between 2-4 weeks, with the underlying skin being initially hypo- or hyperpigmented; scarring is rarely observed after the infection is completely resolved. The course of the illness may be prolonged in immunocompromised patients.

Herpetic Gingivostomatitis is diagnosed primarily through clinical examination , since the appearance of lesions, the localization, and the accompanying clinical picture are highly specific for this infection. In addition, the diagnosis can be confirmed through several tests:
- Serology - increased titers of anti-HSV IgM antibodies in primary infection, and increased titers of anti-HSV IgG antibodies in recurrent infections  .
- Viral cultures - the Tzanck test comprises tissue sampling from freshly ruptured vesicles and Wright-Giemsa staining of the material reveals multinucleated giant cells .
- Biopsy of lesions, direct immunofluorescence and polymerase chain reaction (PCR) testing may serve as alternative diagnostic procedures, but they are used in some other circumstances (eg. PCR techniques are used when suspecting herpes encephalitis).
Serology and viral cultures are the methods of choice for confirming the clinical suspicion of a herpes infection . Additional tests should be performed if these recurrences are frequent, to rule out possible underlying illnesses that predispose the patient to these infections, including HIV testing and malignancy.

This infection is self-limiting and it can resolve without treatment. However, when patients experience symptoms such as pain and high fever, symptomatic therapy may be given to reduce the burden of the disease. When the infection is severe, antiviral therapy may be initiated in order to reduce the duration and severity of symptoms . Acyclovir is an antiviral agent that is used primarily for treatment of herpetic infections and it can be used either topically or systemically.
Initially, herpetic gingivostomatitis is managed through symptomatic therapy, such as administration of acetaminophen or ibuprofen. Occasionally, local anesthetics such as dyclonine 0.5% liquid or benzocaine ointment are used directly with a swab to reduce pain.
If antiviral therapy is necessary, which is the case in severer infections, acyclovir can be administered locally, as a 5% ointment, six times daily for about 7 days. Penciclovir 1% cream is an alternative treatment and is applied every two hours for 4 days . Oral therapy for herpetic gingivostomatitis includes acyclovir 15mg/kg PO five times a day for children, for seven days. Other antiviral agents that may be used include valacyclovir and famciclovir.
Primary gingivostomatitis is a self-limiting benign disease, which sometimes resolves without any treatment. Typically, it lasts for about 10-14 days, sometimes up to 3 weeks, when lesions spontaneously subside. Symptomatic, and sometimes antiviral therapy is necessary and in some cases, if the lesions are somewhat larger, a secondary bacterial infection may occur, which may require local antibiotic therapy.
Recurrences of gingivostomatitis may occur and they are usually triggered by certain factors that suppress the activity of the immune system. Like primary infections, they are also self-limiting, but may be debilitating and frustrating for patients if they recur more often.
Gingivostomatitis is one of the many forms of infection caused by the two herpes viruses : HSV-1 and HSV-2, with HSV-1 causing about 80-90% of cases  . Herpes simplex virus is a double-stranded DNA virus, which establishes infection by penetrating the mucosal membranes and skin after direct inoculation through contact with infected individuals. Once it reaches the skin, it causes lysis of the cells and development of vesicles that are hallmarks of this disease. After causing the primary infection, herpes virus infects the innervating neurons and travels to the ganglia (most commonly the trigeminal ganglia), where it remains dormant. This is the reason why herpes virus can cause recurring infections, although our immune system, mainly CD8+ T cells, suppresses its replication.
This infection is most commonly observed among children and young adults, although it can be seen in patients of any age and sex. It is estimated that up to 90% of the population has already contracted the virus by the age of 40 and up to 40% of individuals that harbor the virus have recurrent infections  .
The virus is transmitted from person-to-person, through close or direct contact with the skin or mucosa of the infected individual. HSV-1 is transmitted through hand and oral contact, mainly through saliva, while HSV-2 is primarily transmitted through sexual contact (responsible for the vast majority of genital herpes infections). A growing incidence of HSV-2 as a cause of oral herpetic infections has been observed, which was not the case in the past .
Individuals at risk of contracting the infection are those who are in close contact with people exhibiting an active infection. Gingivostomatitis is a self-limiting infection and may even have an asymptomatic course, which makes it a rather benign illness. However, recurrent infections may occur, most likely due to a compromise of the immune system, which enables the virus to replicate and re-establish infection. Certain factors that may trigger such events include UV radiation, emotional and physical stress , menstruation, and long-term immunosuppression such as chemotherapy, infection by human immunodeficiency virus (HIV)   , or immunosuppressive drugs. It may also appear if high fever is present, which is why gingivostomatitis is sometimes called "fever blisters".
The virus is shed during active infection and up to three weeks after the infection is resolved, which illustrates that direct and close contact during this time period should be avoided, in order to prevent transmission of the virus.
Once herpes virus is inoculated into the skin, it causes lytic infection of cells at the site of infiltration. Through lysis of cells via degradation of host cell DNA and disruption of the cytoskeleton, it causes tissue injury and avoids the immune response by travelling from cell-to-cell and avoiding the extracellular environment where it can be targeted by the immune system. Once it replicates at the site of initial infection, the virus migrates into the innervating neurons and travels to the sensory nerve ganglia where it remains dormant, most commonly reaching the trigeminal ganglia. The use of neurons as sites of replication and travel are likely the cause of pain that can sometimes be debilitating.
Although gingivostomatitis is usually a result of primary infection by HSV, reactivation of the virus from sensory ganglia may occur and cause recurrent mucocutaneous infections in the same perioral and oral regions. However, these infections are usually milder in their course and have a shorter duration, due to the existence of immune memory. A more effective immune response is mounted under such circumstances.
Transmission of the virus, as mentioned previously, occurs through close or direct contact with secretions or lesions of an individual with active infection, but transmission may also occur weeks after resolution of the infection. For these reasons, preventive strategies include avoiding contact with these individuals, particularly during the active phases of infection, together with proper hygiene measures. Sharing of glasses, toothbrushes, eating utensils and other materials that may contain saliva of individuals affected by this disease should be avoided.
Herpetic gingivostomatitis is one of the most common clinical manifestations of primary herpes simplex virus infection . Herpes simplex type 1 (HSV-1) is responsible for the majority of infections, while herpes simplex type 2 (HSV-2) is the causative agent in only a small number of cases . This type of infection is most commonly observed in children, but it may occur in any individual. The virus is contracted through close contact with individuals who shed the virus, such as those with active infection. It is not uncommon for the condition to be "asymptomatic", but typical presentation is the appearance of erythematous and grouped vesicles in the oral and perioral area, with or without further symptomatology, such as pain, excessive salivation and fever. Other symptoms, such as lymphadenopathy, malaise and headaches may occur and vesicles often burst and lead to the development of perioral ulcers and crusts. It is a self-limiting disease and can spontaneously resolve, or it can sometimes require symptomatic, even antiviral therapy. However, children may be greatly disturbed, refuse to eat and drink, and sometimes need rehydration therapy. Prevention is achieved through avoiding close contact with individuals who have an active infection. It is important to clarify that herpes virus infection can recur, due to the fact that after the primary infection, the virus remains dormant in nerve ganglia. Gingivostomatitis is one of the most common manifestations of an initial infection by herpes virus.
Herpetic gingivostomatitis is a painful viral infection of the gums and other parts of the mouth caused by the herpes virus. The infection results in reddish skin and tiny vesicles that rupture and turn into crusts, usually occurring on one side of the face. Infection most commonly occurs in children, and when it does, it is most commonly a "primary infection", meaning that it is the first time they are encountering the herpes virus. From then on, recurrent infections may occur, as the virus "sleeps" in neurons of the face after the initial infection. Symptoms such as fever, pain at the site of infection, enlarged lymph nodes, etc. may occur, and children may often feel weak and refuse to eat and drink due to pain. The physician should recognize the typical appearance of the skin lesions and immediately suspect this infection, but a definite diagnosis is achieved through swabs from the affected skin and further testing. This infection can last up to a few weeks, after which it resolves, usually without any signs of scarring on the skin. Recurrences may occur later in life. Treatment may be necessary if the infection does not resolve on its own and includes application of local anesthetics, or sometimes antiviral agents on the affected skin. In rare cases, oral intake of antiviral agents, such as acyclovir, may be necessary to treat this infection.
